Donny, You did the right thing installing shims per Steve's advice. If the adjustment substantially reduces the bump steer that you were experiencing then you are good-to-go, unless you care to measure what you now have and try improving it further with more adjustments by using measurements. You might or might not "feel" additional improvements. A lot depends on what you are comfortable with. If your sense is that the shimming has eliminated bump steer then you found the number that works for you and your car setup.
Sorry for the suspension geometry 101. Apparently that offends some people. It's my nature to thoroughly understand a mechanism before I start modifying it. It's sometimes easy to put the cart before the horse so I share what I know in hopes to be helpful.
BTW, Great to see you found a willing helper. Give him a few years and you will be his helper
